Short description of error
Selecting a sequence of vertices that makes up a face don't select the face. The resulting selection also only contains some of the edges.

Exact steps for others to reproduce the error

  1. Delete the default scene
  2. Create a UV sphere
  3. Select four vertices that make up one of the sphere's faces

Only three edges are selected, and no faces are selected.

Another example: after selecting these six vertices from the top left in a clockwise order, I wind up with these edges selected:

This can also happen when selecting edges. Four edges on a face are fine, but six edges around two faces wind up selecting neither face.

Need to select verts individually or with circle select to reproduce the issue. Box select works fine so far.

Marking this as high priority because this is regression
